SPECIFICATION forming part of Letters Patent N0. 761,431, dated May 31, 1904:. I Application filed il'auuary l1l 1904. Serial No. 188,663. (No model.)

To all iii/"2.0m it may concern.-

Be it known that we, WILLIAM H. WAGONER and-JAMEs ADAMS, citizens of the United States of America, residing at Monesson, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the following is a" specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in wrenches, and has for its object to provide a wrench which may be readily adjusted to any desired position.

Another object of our invention is to provide a wrench wherein the ordinary threads generally used are entirely dispensed with,

means being provided whereby the sliding jaw may be easily and quickly adjusted and readily held in this position during the use of the wrench.

Briefly described, the improved wrench consists of a shank having a fixed jaw, and upon this shank is adapted to be moved the sliding jaw, having pivoted thereina lever which engages the shank "of the wreneh and firmly holds this jaw in any desired position.

The invention further consists in the novel construction, combination, and arrangement oi arts to be here nafter more fully described,

and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings,

forming a part of this application, and wherein like numerals of reference indicate like parts throughout the several views, in which' Figure 1 is a side elevation of our improved wrench. Fig. 2 is a vertical sectional view, a portion of the wrench being broken away. Fig.3 is an edge view thereof, Fig. 4; is a horizontal section taken on the line 4: L of Fig. 2. l

In .carrying out oufrinvention we employ a shankl, having on its lower end a suitable handle 2 and carrying upon its other end the fixed or stationary jaw 3, and in the shank l of thewreneh we provide a groove i the entire length of the shank and the handle, and

' The block"? is carried between the side walls The lower portion of 8 of the slidable jaw 9. the block 7- is cut away, as indicated at 10, to allow slight movement of the lever 5, which is pivoted in the recess 11 by the pin 6, the upper end 'of this lever being rounded, as indicated at 12, whereby a cam-surface is provided which engages the base 1 1 of the groove 4:, the lever extending down in the groove 4, and in the position of the sliding jaw 9, as illustrated in the drawings, the leverslightly projects beyond the handle 2, whereby when the jaw is closed the lever will be the same length as the shank and handle of the wrench.

When it'is desired to operate or move the sliding jaw of the wrench,the wrench is held in one hand, while'the sliding jaw ismanipulated by the lever with the other hand, and it being desired to hold this jaw in any position upon the shank the lever 5 is pressed inwardly, engaging the base 14 of the groove and forcing the rear part of the jaw 9, including the block 7, outwardly, impinging the side of the jaw, as indicated at 15, against the shank,

whereby the jaw is firmlyand securely held in this position until the lever is raised and the cam-surface 15 permitted to lie loose pensive construction of wrenches heretofore used, and while we have herein shown the preferred 'form of construction it is obvious that various changes may be made in the details of construction without departing from the general spirit of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A wrench comprising a shank having a handle upon its one end, and a stationary jaw upon its other end, said shank having a groove formed its entire length and extending into the handle, a slidable jaw mounted on said shank, said jaw having pivoted therein a lever to engage within the groove of the shank, substantially as described.

5 2. Awreneh of the character described comprising a shank having a stationary jaw on its one end and a handle on its other end, said shank and handle having a groove formed therein, a slidable jaw mounted upon said IO shank, said jaw having a lever pivoted therein, the upper end of said lever being rounded to engage the base of the groove, substantially as described.

In testimony whereof we aflix our signatures in the presence of two witnesses.
